No, we should not pay attention to these opinions. (Find the essay below)
Explanation:
Celebrities are people who are prominent or well known because of the work that they do. Actors and sports stars are rightly classified as celebrities because their work affords them a lot of exposure. We see them on television, the internet and social media, and hear about their deeds and accomplishments on the radio.
This group of people always have their opinions about life and other topics of interest which they air when interviewed or when they decide to volunteer the information on their own accord. Most times fans who love them value their opinion so much that they even adjust to them or view it as the standard. For these fans, celebrities are their role models. They tend to copy their hairstyles, modes of dressing, and their opinions! Advertisers key to this fact when they use them to promote their goods.
It is very wrong to hold the opinions and actions of celebrities as the gold standard because they are imperfect and are prone to mistakes. Celebrities are just like any other one of us who have opinions or behave in ways that are sometimes wrong. Copying their every move, action, and opinions would be potentially damaging to us. Their opinions should be taken with a pinch of salt.
It is important that while fans maintain the love they have for their favorite celebrities, they also endeavor to have a mind of their own. Each person should know what works for him or her and live by such. It would be a great mistake to be easily carried away by the opinions of others.
Conclusively, balance is key. Love for celebrities should never cloud an individual's thinking. When this is done, future heartaches that come from adhering to wrong opinions can be avoided.
Answer:
Part a)

Part b)
force is 21.2 times more than the weight of the person
Explanation:
Part a)
As it is given that the distance after which he stopped is given as
d = 1.50 cm
here finally it stops so final speed is given as

initial speed is given as

now by the equation of kinematics we know that



Now the force on the leg is given as

m = mass of leg = 13 kg


Part b)
Force due to weight of the object

here we know
M = 75.0 kg


Now we know that the ratio of the weight with the force on leg is given as

so force is 21.2 times more than the weight of the person
